Annihilation of the solar system

At the Space Force Combat Command Center, everyone was silent. They watched helplessly as the large ice block moved along the boundary of the effective range of the space turrets, and they avoided the 12-minute firepower pouring from the two space turrets without making a single extra move.

If these 12 minutes of firepower were applied to the Alps, the famous mountain would only appear in the photo forever, replaced by a crater-like crater with an altitude of more than 100 meters lower.

"Report! The target's infrared signal has weakened!" the technical officer reported.

In the orbit simulation picture on the large screen in the command center, the large ice block circled the arc of the effective range for more than half a circle and returned to a straight track.

"According to the target's current orbital parameters, it will still pass by the Earth at high speed from a position of 1 million kilometers above the Earth's 30 degrees north latitude," the staff report reported.

"In other words, after it bypassed the space turret, it returned to its original orbital position." Xia Lan said.

"But why does it do this? The current orbital position is meaningless to it!" the staff member asked in confusion.

Xia Lan shook his head slightly and said nothing.

"Order the lunar laser defense system to enter combat status! In addition, let them prepare fire control and out-of-bounds irradiation plans and be ready to fight at any time!" Chai Shizheng issued the order.

"There are laser transmitting towers on the front and back of the moon. The focusing prism in the moon's orbit allows the laser beam to have almost unlimited range. Let's see how you hide now!" the staff officer stared angrily at the blue thermal imaging image of the big ice cube.

said.

Xia Lan was startled and said to himself:

"Moon..."

Then she started typing on the computer. Although her voice was very low, Chai Shizheng and several staff officers heard it. They were all quietly waiting for the results of Xia Lan's calculations on the computer without questioning her.

.Soon, Xia Lan left the keyboard with her hands and slowly leaned on the back of the chair. Her eyes were blurred and she sighed deeply.

"Dr. Xia Lan, have you made any new discoveries?" Chai Shizheng asked.

"There is no need to activate the lunar laser defense system." Xia Lan's words were filled with a deep sense of powerlessness.

"What?" the staff officer exclaimed.

Xia Lan put a simulated orbit map on the big screen. It was a very simple top view. The earth was in the middle, the moon was on the left, and there was an inclined line on the right. If the moon was used as a light source

, the position of that diagonal line is just in the shadow formed by the earth's obstruction.

"This oblique line is the predicted trajectory of the big ice block after it enters the range of the Lunar Laser Defense System. It will be just within the shadow of the Earth blocking the moon's laser path. Now, we finally know why it takes such a strange trajectory.

The route is to avoid the lunar laser defense system." Xia Lan said.

"Can't the laser system be allowed to fire in advance?" the staff officer asked excitedly.

"The killing principle of high-energy lasers is energy focusing. For the refracting prisms created by our current engineering technology, the beam divergence becomes more serious after it exceeds 2 million kilometers. Coupled with the high reflectivity of the ice itself, the damage effect may not be obvious.

"Xia Lan explained.

"Then our laser defense system will be useless against subsequent ice crushing belts and spore swarms. They can avoid laser irradiation in the same way!" said the staff officer.

"That's not true. The current orbital position of the moon relative to the earth is very special. The target is a single individual, so this situation occurs. We have calculated the orbit and found that hundreds of thousands of kilometers of broken ice belts and spore groups enter

When the laser system is in range, the orbital position of the moon is very ideal." Xia Lan's words somewhat calmed the depressed mood of several staff officers.

"Then what does it want to do after hiding in the laser shooting blind spot on the back of the earth?" the staff officer asked.

"It will change its orbit and then hit the earth!" Chai Shizheng, who had been silent until now, spoke.

Xia Lan nodded solemnly:

"This is the most likely possibility. If an ice cube of this mass falls on the top of any large city, it can wipe out all the population in that city. And where exactly it falls may have to wait until it starts to enter the outside world.

You can only know when there is a layer of atmosphere.”

The command center was silent, the staff stood there in despair, and the technical officers could only sit blankly in their positions and were at a loss. Chai Shizheng stared angrily at the big ice block on the big screen that was about to enter the blind spot.

, his eyes were burning with anger, and the wrinkles on his brows were a little deeper.

"Order the 'Dome Armor' system and the 38th Space Group Army to enter first-level combat readiness and prepare to start low-Earth orbit interception. Apply to EDA to implement the 'Kite Plan'!" Chai Shizheng finally issued the order. Staff officers and technical officers immediately began to implement it.

command, but Xia Lan saw from their expressions that the last "Paper Kite Plan" made them all a little anxious.

Zhou Cheng and Shen Manling also saw the whole process of the failure of the synchronous orbit interception in the secret service's underground preparation command center. Zhou Cheng gritted his teeth and was about to turn around to say something to Cao Rui. Only then did he realize that Cao Rui had been beside him before.

Rui, I don’t know when he disappeared.

Just as he was looking around, Cao Rui hurriedly walked over from the crowd. Before Zhou Cheng could ask questions, Cao Rui whispered:

"Lao Zhou, sister-in-law. Come with me. Don't ask any more questions. Let's go first."

As he spoke, he kept paying attention to the performance of the people around him, trying not to attract anyone's attention. Zhou Cheng and Shen Manling were both startled, but they didn't ask any more questions, and just followed Cao Rui silently and disappeared into the crowd.

Cao Rui led Zhou Cheng and his wife to the corner of the underground garage. After getting into the car, Cao Rui drove onto the highway from an unknown exit.

Because of the evacuation alarm that was sounded before, the city roads are now deserted in a real sense, and not a single person can be seen. Both the military and armed citizens have entered bunkers, and the sky is a different scene. Groups of fighter jets.

Or helicopters would roar overhead from time to time.

"Old Cao, where are you going when you bring us out so mysteriously?" Zhou Cheng stared at Cao Rui with a question mark on his face.

Cao Rui pointed to a police light in front of the windshield in front of Zhou Cheng.

"Put this on the roof of the car. This will set off the emergency alert and put the whole city under curfew. Install this thing to avoid trouble."

Zhou Cheng followed Cao Rui's instructions and put the police light with magnet on the roof of the car. As soon as he sat down, Cao Rui handed over a cigarette:

"Lao Zhou, have you seen these cars on the roadside?"

"What car?" Zhou Cheng said while looking towards the roadside. Only then did he realize that there were many civilian vehicles parked on the roadside. But the way these cars were parked was very strange. They were not parked along the roadside as usual.

Instead, it is parked on the side of the road at an angle of 45 degrees to the road.

"These cars are driven from underground garages or open-air parking lots to the roadside and placed like this," Cao Rui said.

"Why are they arranged like this?" Zhou Cheng asked, obviously he had forgotten the question he had just asked.

"None of these cars have handbrakes. When needed, you only need to push them to the middle of the road to form barricades. If they are no longer needed, push them back to the side of the road and it will not affect normal traffic," Cao Rui explained.

road.

Zhou Cheng looked at the rows of cars of various types parked diagonally on the roadside and nodded slightly, and was about to ask a question. Cao Rui said with a smile:

"Lao Zhou, take a closer look. Maybe your Land Cruiser is right here."

"Impossible, after so many years, that car should have been refurbished. Hey, I still miss my car quite a bit." Zhou Cheng sighed.

"That was your treasure back then, and I have never driven it. I still remember when you were installing the radio antenna. Because the opening was a little too big, you caught the mechanic and refused to let him go, and later he had to pay for it all the time.

I won’t stop until I get the money.”

Cao Rui and Shen Manying both laughed. They just talked about the past and laughed all the way. The car drove to the suburbs of the city.
